【摘要】 本文以太原钢铁集团技术改造为课题背景,设计了一套EPC电液伺服系统。 EPC (Edge Position Control)即边缘位置控制,广泛应用在轧钢或钢带热处理等连续生产线中,用来对带材连续生产进行卷齐控制。 本文设计的EPC系统由光电传感器、PLC、液压站及卷取机组成。光电传感器采回位置信号后经西门子S7-200处理,再将处理后的信号经放大后传给液压站,最后推动卷取机跟随带钢的位置变化。系统的设计分为主体液压部分和控制部分。主体液压部分设计包括主要液压元件的选型及整个液压系统的搭建。控制部分的设计包括PLC及其附属器件的选型及伺服放大电路板的设计。系统软件的设计包括PLC程序设计及MATLAB仿真软件SIMULINK的设计。 本文在介绍了主体液压系统和控制系统的主要结构及具体设计内容后,重点分析了整个系统的控制性能,并相应的提出更多还原

【Abstract】 This paper introduces the EPC electro-hydraulic servo system. This EPC system is one of the Taiyuan Iron and Steel (GROUP) CO.,LTD’s technical reformation program.EPC (Edge Position Control),applied in rolling mill, is designed to realize the control in tension, position, thickness and speed ,etc.This EPC system, which is designed in my paper ,make up by photoelectric sensor, PLC, hydraulic equipment and a roller that is used to rectify deviation. The EPC’s work flow is shown as follows: At first the photoelectric sensor adopts the position signal, then the signal is dealt with by Siemens S7-200 and amplified for the hydraulic equipment to stand, at last the roller which is controlled by the hydraulic equipment rectifies a deviation according as thetreated signal. The design of the systematic hardware is divided into some of hydraulic pressure and electric part. Hydraulic pressure design includes selecting the component’s type and setting up the whole hydraulic pressure system. Electric design includes selecting the type of the PLC and drawing the enlarge circuit. The design of the system’s software includes the programming Of PLC and the MATLAB artificial software SIMULINK.After recommending hydraulic pressure system and electric system’s main structure and concrete content, this paper have analysed the control performance of the whole system especially and corresponding proposed the Fuzzy PID control algorithm.Systematic emulation and industrial test are proved: Fuzzy PID control method has improved systematic control performance greatly.更多还原
